Abstract
A method to improve the quality of aerial triangulation for photographs in coastal areas is proposed. Uneven distribution of ground control points and tie points due to the presence of sea water causes the aerial triangulation to produce a systematic error, which is represented by elevation difference of ground control points between stereo model surface and real topography. Compensation of the elevation difference is given to the ground control points with which the following triangulation corrects exterior orientation parameters so as to match stereo model surface to real topography. An experimental study using historical photographs for beach environment, GPS surveys of ground control points and independent check points demonstrates that the proposed method gives RMSE of the elevation difference less than 0.1 m.
